6 Problem Solvers in Your Doctor's Medicine Cabinet

Must Have: Moleskine

Doctors agree that sometimes you just need a BandAid to protect a wound, but when treating blisters or hot spots, BandAids can cause rubbing that will make the problem worse, says Cathleen London, MD, an assistant professor of medicine at Weill Cornell Medical College and an assistant attending physician at New York-Presbyterian Hospital. Instead, she recommends cutting a circular piece of adhesive moleskine that extends past the edges of the affected area. "You're building up the skin around the blister," she says. The moleskine will stay comfortably in place while the blister heals on its own.

Caution: You can usually leave it on until it falls off, but change the dressing if you experience itching or irritation.
